About the Breadboard power supply board hardware design

Breadboard power supply board hardware design is an open source PCB design by SolderedElectronics, published on GitHub under the TAPR-OHL-1.0 license. It is a 2-layer board measuring 54 × 29.5 mm, with 24 components from 17 distinct parts.

Other key parts include the 7805 and SE5218. By type, the board carries 6 relays, 4 capacitors, 3 switches, 3 diodes, 3 resistors and 2 ICs.

It belongs with the power & battery and dev boards & breakouts designs in this gallery.

From the project

Hardware design, BOM, gerbers and 3D files for Breadboard-power-supply-board designed by Soldered Electronics.

If you need a simple and stable power source for your breadboard projects, this board is here to help. Supply it with DC jack DC power or using UCB-C cable, and the board provides 3.3V, 5V or 12V directly to the power supply lines on the breadboard. Output voltages are adjustable seperately using the onboard switches. There’s a power LED, a power switch and an automatic voltage selection circuit, in case both power inputs are there.
